The Android 5.0 Lollipop release date version has removed the Silent Mode features on mobile devices that were updated.

“The missing Silent Mode is only seen on devices that run the Lollipop system firmware,” the Tech Times writes in a review of the phone.

“Users whose devices have been stripped off the silencing feature are left with certain levels of volume and vibration in their devices.” Android 5.0 Lollipop’s material design has been criticized for “oversimplification.” “The most obvious is that its mission to clean up and simplify Android means that several options that were once on the surface are now buried in menus.

The new Gmail is perhaps the worst offender with only search and compose buttons now available with a single tap.

Mainstream users are unlikely to care, but power users have already expressed frustration,” Forbes writes in a review of the phone.

“Another knock on effect of Material Design’s declutter mission is that everything is more spread out so you get less information on a single screen.

Again Gmail shows this off where about six emails show up before you need to scroll, when before it was possible to get 8-7.” Android 5.0 Lollipop was released last week for the Nexus 5 and several other devices, and some users on mobile device forums have already made criticisms of its features and specs.

Nexus 5 owners are able to install the Android 5.0 Lollipop update via a Mac Terminal by extracting contents from the update’s zip folder and entering a specific command.

The International Business Times has published a step-by-step guide assisting Nexus 5 users. Following the release of the update, Motorola announced the company will include the new Operating System in its own smartphones–a complete update schedule may be found here.

Android 5.0 Lollipop was scheduled for a November 3 Google release date.

The report adds that Google Nexus devices will receive the update first and that Samsung, HTC and LG phones will follow suit. Among the most popular features and specs of the Android 5.0 Lollipop is its Material Design that offers improved animations and application icon updates.
